June 24, 2015 marks the 444th Foundation Day of the City of Manila. The Presidential Communications Development and Strategic Planning Office (PCDSPO) joins the commemoration by publishing a special webpage that examines its rich pre-colonial past, its evolution from a walled city to a megacity, and the significance of the Ultramar—symbol of the city the Spaniards once heralded as the Distinguished and Ever Loyal.
